FAQ

Q1: What is the Yokogawa PW482-10 used for?
It is a dedicated AC input power supply module for Yokogawa CENTUM VP/CS 3000 systems, converting 220–240 VAC into the DC power required by the FCS backplane and associated I/O modules .

Q2: What is the input voltage of the PW482-10?
220–240 VAC ±10% (range: 198–264 VAC), 50/60 Hz ±3 Hz . Do not use it in a 100–120 VAC system — that requires the PW481 variant .

Q3: What are the output voltage and current?
Yokogawa does not publish generic output voltage/current ratings for the PW482-10 because it is dedicated to specific system units. Third-party claims of 24V DC, +12V/+24V, or 40A are not confirmed by official documentation and should not be relied upon . The output is designed to meet the specific backplane requirements of compatible Yokogawa units.

Q4: Does the PW482-10 support redundancy?
Yes. Two identical modules (matching suffix codes) can be installed in slots P1–P2 for dual-redundant operation. A single configuration uses P1 only .

Q5: What is the difference between PW481, PW482, and PW484?
They differ primarily by input power: PW481 = 100–120 VAC, PW482 = 220–240 VAC, PW484 = 24 VDC. They are not interchangeable .

Q6: What does the -10 suffix mean?
The -10 suffix indicates a specific variant/revision of the PW482 module. Match the full ordering code to the existing module before replacement. Do not assume equivalence with other suffixes (-50, -51, -E0, -E1) .

Q7: Is the PW482-10 a current or legacy product?
It is listed as legacy/discontinued and is primarily available as replacement spare stock for existing CENTUM CS 3000/VP installations. Confirm availability and condition with Yokogawa or an authorized distributor .

Q8: Where can I get technical documentation?
Official Yokogawa documentation (General Specification GS 33J60E70-01EN) or an authorized distributor is the authoritative source for specifications and compatibility .
